ALWAYS CARRY AIR BAG (INFLATOR) MODULE
WITH TRIM COVER (AIR BAG OPENING) AWAY
FROM BODY.
10B-58 AIR BAG SYSTEM
LIVE (UNDEPLOYED) AIR BAG (INFLATOR) MODULES
Special care is necessary when handling and storing a live (unde-
ployed) air bag (inflator) modules.
The rapid gas generation produced during deployment of the air
bag could cause the air bag (inflator) module, or an object in front
of the air bag (inflator) module, to be thrown through the air in the
unlikely event of an accidental deployment.
WARNING:
Never attempt to measure the resistance of the air bag (in-
flator) modules (driver and passenger). It is very dangerous
as the electric current from the tester may deploy the air
bag.

Never attempt disassembly of the air bag (inflator) modules.

If any abnormality is found, be sure to replace it with new one as
an assembly.

When an abnormality is noted as existing in the live (undeployed)
air bag (inflator) module, be sure to deploy it before discarding it.

When grease, cleaning agent, oil, water, etc., got on the air bag
(inflator) modules (driver and passenger), wipe it off immediately
with a dry cloth.

If air bag (inflator) module was dropped from a height of 90 cm (3
ft) or more, it should be replaced with a new one as an assembly.
WARNING:

For handling and storage of a live air bag (inflator) module,
select a place where the ambient temperature below 65
C
(150
F), without high humidity and away from electric
noise.

When carrying a live air bag (inflator) module, make sure
the bag opening is pointed away from you. In case of an
accidental deployment, the bag will then deploy with mini-
mal chance of injury. Never carry the air bag (inflator)
module by the wires or connector on the underside of the
module.
Otherwise, personal injury may result.

OPENING) UP, AWAY FROM LOOSE OBJECTS.
1. Slit on workbench

AIR BAG SYSTEM 10B-59
WARNING:
When placing a live air bag (inflator) module on bench or
other surface, always face the bag up, away from the sur-
face. As the live passenger air bag (inflator) module must be
placed with its bag (trim cover) facing up, place it on the
workbench with a slit or use the workbench vise to hold it
securely at its lower mounting bracket.
It is also prohibited to place anything on top of the trim cov-
er and stack air bag (inflator) modules.
This is necessary so that a free space is provided to allow
the air bag to expand in the unlikely event of accidental de-
ployment.
Otherwise, personal injury may result.
LIVE (INACTIVATED) SEAT BELT PRETENSIONERS
Special care is necessary when handling and storing a live (inacti-
vated) seat belt pretensioners.
Also, when the seat belt pretensioners activate, gas is generated
and the seat belt is retracted into the retractor quickly.
Note, therefore, that if they activate accidentally, the seat belt pre-
tensioners and other object(s) around them may be thrown through
the air.
WARNING:
Never attempt to measure the resistance of the seat belt pre-
tensioners. It is very dangerous as the electric current from
the tester may activate pretensioner.

2. Ground
3. SDM case ground
AIR BAG WIRE HARNESS AND CONNECTORS
Air bag wire harness can be identified easily as it is covered with a
yellow protection tube. Be very careful when handling it.

When an open in air bag wire harness, damaged wire harness,
connector or terminal is found, replace wire harness, connectors
and terminals as an assembly.

When installing it, be careful so that the air bag wire harness is not
caught or does not interfere with other parts.

Make sure all air bag system grounding points are clean and
grounds are securely fastened for optimum metal-to-metal con-
tact. Poor grounding can cause intermittent problems that are dif-
ficult to diagnose.
DISPOSAL
Do not dispose of the live (undeployed) air bag (inflator) modules
and the live (inactivated) seat belt pretensioners. When disposal is
necessary, be sure to deploy the air bag according to deployment
procedure described under ªAir Bag (Inflator) Modules Disposalº
and to activate the pretensioner according to activation procedure
described under ªSeat Belt Pretensioners Disposalº.
WARNING:
Failure to follow proper air bag (inflator) module and seat
belt pretensioner disposal procedures can result in air bag
deployment and pretensioner activation which could cause
personal injury. Undeployed air bag (inflator) module and
inactivated seat belt pretensioner must not be disposed of
through normal refuse channels.
The undeployed air bag (inflator) module and inactivated
seat belt pretensioner contain substances that can cause
severe illness or personal injury if the sealed container is
damaged during disposal.

If any faulty condition is found in above checks, replace faulty
part.

Steering wheel and driver air bag (inflator) module
± Check for damage or air bag (inflator) module fitness.
± Check trim cover (pad surface) for cracks.
± Check wire harness and connector for damage or tightness.
If any faulty condition is found in above checks, replace faulty
part.

Contact coil and combination switch assembly
± Check wire harness and connectors for damage or tightness.
± Check contact coil case for damage.
If any faulty condition is found in above checks, replace.
